This part is junk, lasted 3 months then died. MSD used to be good top of the line but now everything thing I've bought from them since February this year has been junk. Don't know if it's because of staff shortages or what but quality control hasn't been worth a crap lately. Do not waste your money on this part.

I put this on my 89 ford 302 and it works great, no problems running it hard for a few months now. May even rev up a bit better than the old set up and the reve limiter works and is fun to set at different rps.

This is a great little product to add spark reliability, even at high RPM, without forking over the big bucks for a full Multiple Spark Discharge system. It still keeps the stock appearance of a regular HEI with some good perks. Even with the right idle mixture, there were a few misfires every now and then but this seemed to clear it up very well. The rev-limiter function is very easy to use and can help prevent over revving that could cause engine damage. Overall, I noticed a better low-end throttle response and SLIGHTLY better miles-per-gallon. Install was extremely easy and has not given me any issues at all for the time being. I am one satisfied customer.
